THE DUNEDIN DRAINAGE SCHEME.

TO THK EDITOR. , In your; Monday’s issue I read with interest an article (contributed) giving an account of the complex doings of the Drainage Board. It is a matter which ‘ has greatly puzzled both amateur and professional engineers, including the majority of the memoera of the Board ; but thanks are due to your contributor, who has put the present position plainly, so that an ordinary or intelligent ratepayer can understand the muddle wo are in. What the future will bo for tho City and suburban ratepayers and citizens, who will suffer indirectly, time alone will show when the £200,000 loan runs drv. 'lhen we’ll know where we arc when its too late. What I am puzzled about is the engineering difficulty to lie overcome in the construction of the main sewer in the North-east Valley (familiarlyknown as Prohibition Valley) roadway, as t> how it will connect with the King street sewer at the Leith bridge, because from Lindsay’s Creek at the bridge the sewage, paradoxical as it may seem, will have to run uphill. If lam wrong, it will please mo to bo corrected, as I am under the impression that tho bed of Lindsay’s Creek is 15ft or 20ft.lower than the northern inlet of the fling street sewer. That being so, a suction or some other patent pump will bo required to draw the Valley sewage into the City sewer, which is too small already for present purposes, without trying to absorb suburban fluids and other mixtures en route to Tomahawk Head.—l am, etc., Leith.
